Revelation 8:12-13 - The Fourth Trumpet
12 And the fourth angel sounded, and the third part of the sun, and the third part of the moon, and the third part of the stars, were smitten; and the third part of them was darkened, and the day did not shine the third part of it, and likewise the night.
13 And I saw, and I heard one eagle flying in the midst of heaven, saying with a great voice; Woe, woe, woe, to those dwelling upon the earth, on account of the other voices of the trumpet of the three angels, who are about to sound.
